INJECTOR.

Specification of Letters Patent. Patented sept fijz 19 14,

a lication filed February 19, 1914. Serial No. 819,606.

Be it known that I, 'Emv'sr Konn'rmo,

subjectof the Emperor of Germany, residing at Pe'gli, in the Province of Liguria, in

the Kingdom of Italy, haveinvented certain new and useful Improvements in Injectors, of, which the following is a trueand exact description, reference being had td-the accompanying drawings, which form a part thereof. i W p My invention r'elatestdboil'er feed injec-,

tors and has for its object to provide a device especially adapted for economically feeding hot water toga boiler.;

Broadly. speaking niy invention consists in combining with an: injector proper, preferably a two tube injector, a. steam jet pump and a feed water heater situated between said pump and-;th e injector so that the feed.

' water is IELISBd'HICPIGSSUIB by the jet pump,

then heated irr'the feed water heater. and then fed through the injector to the boiler. A special feature of my invention con sists in the construction of a'special casing adapted to contain the jet pump and in: jector and to be combined with them and a feed water heater as described. Y

The nature. of my invention Wlll be best understood as described in connection with the. drawing, which is a sectional elevation showing the casing, the jet pump and in jectors and their connection witha feed water heater and in which- A is the casingv having a steam .inlet B.

leading'to achamber B, from which lead the steam ets 0, C: and C eontrolledby valves I), and D which are actuated by a hand lever D, acting through rod D and "cross bar (Di;

= to it the return tubes 1 leading to an annular header chamber I, which connects through a conduit H with the chamber G in the casing A. The body I of the heater I is filled with exhaust steam and the heater indicated is of the surface condenser type.

" The chamber G'delivers the, feed wateret the increased pressure imparted by the jet pump and increased temperature imparted by-the feed water heater to the injector tube F which delivers it with increased pressure to chamber J whence it passes through injector tube F to chamber K and thence through port L and valve Mtothe boiler.

N is a valve chamber connecting as shown with chambers G, J and K, throu h posts 0, O and O and with chamber N port N leads to the atmosphere. P is a valve stem connected to valve P,

om which 7 carrying valve P at its lower end and cham-' I bered so as to progressively close the ports as the valve is moved. Usually the valve P iscontrolled from the lever D as throu h eccentric Q, rods Q, eccentric Q, and yo e Q connecting it to rod P. The overflow valve, starting lever and connections are all of familiar types and are not therefore fully illustrated or described.

.It is of c'oursewell'known that a boiler injector will not under ordinary conditionsfeed water even approaching a temperature of 212 F. W'ithlthe combination of the jet pump and feed water heater to raise the pressure and temperature of the water fed to the injector tubes proper'the injector can be made to successfully feed water of 212 F. to a boiler and the water can be raised to this temperature without an excessive use of livesteam and hence with economy.

.Having now described my invention, what a I claim as new and desire to secure by Letters Patent is, 1. A boiler feeding device for feeding hot water consisting of an injector in combination with a steam jet pump and a feed water heater connected to. receive water from the jector.

3. A boiler feeding device for feeding hot Water consisting of a casing having separate chambers for a steam injector and for a steam jet pump with. separate feed water and delivery ports for each in combination with an injector and a steam jet pump situated in said casing and means for forcing steam into the injector and pump.

4. A boiler feeding device for feeding hot water consisting of a casing having separate chambers for a steam in ector and for a steam jet pump with separate feed Water and delivery ports for each, incombination with a two tube injector and a steam jet pump situated in said casing and means 101 forcing steam into the'injector and pump tubes.

5. A boiler feeding device for feeding hot water consisting of a casing having separate chambers for a steam injector and for a l l I i i I i I 2.

steam jet pump with separate feed Water and delivery ports for each, in combination with an injector and a steam jet pump situated in said casing, a feed water heater connected to the delivery port of the jet pump and to the feed water port of the injector and means for forcing steam into the injector and pump. v
